. WATER HEATER.

.Applicatiqn' filed Augnst' i5, 1927. serial, No. 213,039'.

My invention relates to Water heaters of the storage type as `used in large building, and Which consists of a tank having one r y plied providing a steam-tight connection and a `tank T tovvhichthe Water to be heated is laborious and time-consuming operation of uncoupling.l the steam supply pipes.

Y Itis a purpose of my invention top'rovide' in ahot Water storage heater, an extremely simple and inexpensive means by Which the heating unit or coil can be readilyremoved or applied Without the necessity of uncoupling. the steam supply pipes, and When ap- With Vthe supply pipes.

I Will describe only one form of Water heater embodying my invention and will then pointout the novel features in claims.

In the accompanying drawings:

Fig. lis a viev'v showingin sidel elevation` and partly in section one form heater embodying my invention;

Fig. 2 is a view showing the heater in end elevation;

Figs. 3 andl 4 are vertical sectional vievvs taken on thelines 3-3 and 4 4 of Figl;

`of Water V5 is a central vertical sectional vievv ofthe header illustrated in Fig. 4.

In carrying out my invention, I provide supplied by a pipe 15 and from Which the heated Water is discharged` through a pipe 16. Within the tank are secured transverse angle bars 17 and longitudinal, angle bars 18, the latter. beingfsecured on the former and substantially coextensive in length -With the tank. The bars l18 arespaced to accommodate acoilof pipe C, andto fixedly position the coilupon the transverse bars 17,

y all in a manner to support the coil centrally adjacent the bottom of the tank.A

The coil C constitutespartof aheating unitfor the Water in the tank T, theremainder of the heating. unit, comprising a header including a stationary part H and a movable part II. The.stationary lpartH consists of -a cylindrical body secured at one end Within Van opening 19 at one end of the tank. l The outer end of the cylindrical body is normally .closed by ahinged door 20 and may besecuredA in closed suitable manner..

. Short vlengths offpipe 21"and 22 extend through suitable 'openings in thecylindrical'A body as clearly illustrated in' Figs. 4iandi 5,

position in any and these pipes are in turnV connected to supply pipes 23 andv24, respectively,

pro-

vided'` With valves'l 25 and 26, respectively,4 4

provided for the purpose ofcontrolling the circulation vof` the heating medium to and' from the header. It Will of course be under- Vstood that thepipes l23 24 are connected to a source of supply such as a `steam boilerV 1 (not shown), thesteam lbeing employed' as the heating medium.l

The movable rpart 5H ofthe header coin-iiy prises a pair of companion velements 27 and 28 in .the formrof metal blocks having outer curved surfaces toconform to thecontour of the cylindrical body, and-flat parallelf` inner surfaces.

extended one end of the coil C, and the' pipe secured therein by threadingA as shown `in Fig. The vertical portions .of the asy Each element'is provided" with L-shaped passages 29 into Whichis` sagesextend'to outer curved surfaces of the` elements for communication with the pipes 2l and 22, so that the latter pipes are placed'r f in communication With the ends vof ,the coil` C.y Suitable gaskets 30 and 3l are interposed between the elemen'ts27 and 28 andv the cylindrical body H, as well as lbetween y the latter elements vand the door 20 .in orderto, prevent the escape of Water as .Will-.be

understood.

The elements27 and 28 are secured in the above described positions by means of an expander which, in the present instance, f comprises a bolt 82, the headgof Which is`V Welded. to the vinner side of ther upperVV element 27 While thelovver end of the boltis countersunk `Within the;inner sidel` of 'the lowerelernent28 as indicated at 33. NA nut 34 is threadedon the loWer en'dof the bolt so as, contact With the flat side Vof the yele-r ment 28. Thus, it Will4 be seen `that by rotation of the nutl the bolt is fed upwardlyl A I through the nut thereby effecting expansion of the elements 27v and '28 into vfirm contact with the cylindrical body.f 'The bolt may be securedin this expanded position bythe provisionof a lock nutj851threaded fonthe bolt above the nut 84. In pactice, the coil C c an'beextendedv into the tank throughthe cylindricalbodyfH so as to. be supported inthe tank by the bars 17 andlS." Inapplying the heating unit the bolt 32'isl adjusted to allovv the elements 27 and 28to occupy what may be termed a contracted position in-order that they may be inserted into the cylindrical body H and Y positioned as illustrated in Figs. l and 5, in

which the passages 29 register With the inner ends of the pipes' 2l and 22.l Once the elements have been positioned as described, the nut 34 can now be manipulated to cause the l bolt 32 to expand the element-s into firm contact With the cylindrical body andV thus secure the passages and pipes in registering closed; position' and by Vopening the valves relation `so that the supply pipes 23 and 24 are placed in circuit communicationy with the coil C. The door 2O is novv secured in 25 and 26 steam or any other suitable heatingV medium is thus caused `to circulate through the coil`C and thereby heat the Water contained Within the tank.

Ifit is desired to remove the coil for purposes of repair or cleaning, as is frequently necessary, the elements 27 and 28 can be moved to contracted position, by manipulation of the nut 34 thereby permitting Withdrawall of the elements from the cylindrical body, and as the coilof pipe is connected to ,the elements it Will be clear that With removal of the elements t-he coil is likewise removed.

1' -When removing the coil C from the tank V 'I`- for the purpose ofremoving scale 'from the surfaceol the pipes oiE the coil or for repairing the joints thereof, the expanding device can be actuated byrotation ol the nut V34 te allovv theV blocks 27 and 28 to *occupyV alcontractedpositionin which they canyb'e readily removed from the cylindrical body II together With rthe coil C. In removing the coil it is impor-tant to note that itis unnecessary to disconnect the pipes 21 and 22 from the cylindrical body H or the pipes 23 and 24 from the pipes 21 and 22, thus eliminating the laborious and time-consuming operationfor'v uncoupling the steam 'supply` Apipes as 1s necessary 1n similar apparatus as y heretofore proposed.

yAll-thoughv I have herein shown and described only one yform of Water heater embodying my invention, it is to be understood thatvarious changes and moc'lifications may be made herein Without departing from the spirit of the invention and the spirit and scope of Vthe appended claims.
